Quality Pet Food: Understanding Biogenic Amines

What Are Biogenic Amines?

Biogenic amines are compounds synthesized during the normal metabolic functions of plants and animals.¹ Many amines play important roles in human and animal physiological functions.^2,3 They can also be present in foods from enzymatic degradation of amino acids due to elevated microbial activity.  At elevated levels biogenic amines can be an indicator of food quality and can become potential health hazards.⁴

Biogenic Amine Formation in Food

Not all biogenic amines have toxic effects and toxicity can vary based on the person or animal affected. Some amines are found naturally in human foods, including meat, fish, cheese, wine, beer, and fermented foods.¹ However, high levels of biogenic amines in food can indicate microbial spoilage.⁵

Accumulation of elevated biogenic amines in food can constitute a potential physiological and toxicological safety risk.

Once biogenic amines are formed, they are heat stable and cannot be destroyed by processing methods such as cooking, baking or canning.⁶ Histamine, tyramine, cadaverine and putrescine are biogenic amines with potential toxicity effects in animals when ingested at high levels.

Amine Toxicity in Dogs and Cats

Even after centuries of domestication, dogs and cats maintain similar genetic profiles to their wild canid and feline ancestors. It’s not uncommon for wild canids and felines to scavenge decomposed or spoiled carcass. Due to this, it appears they have developed adaptive mechanisms to metabolize and detoxify biogenic amines, and domestic dogs and cats may still maintain some of these mechanisms.⁷

There is a shortage of literature evaluating the precise effect of biogenic amines on dogs and cats due to ethical reasons. However, studies have shown elevated levels of biogenic amines can cause food poisoning and detrimental effects on palatability and nutrition. Pet food manufacturers should control biogenic amine formation in raw materials and finished products to avoid detrimental effects to the food or pet consuming it.

Pet Food Safety: How to Control Biogenic Amines

To evaluate product freshness, pet food manufacturers can use the Biogenic Amine Index.⁸ This index shows a biogenic amine ratio in a food product and can be used to indicate the degree of freshness or spoilage.

Kemin recommends implementing Good Manufacturing Practices (GMP) and the methods below to avoid biogenic amine formation and promote pet food product freshness:

• Use quality ingredients: The quality of an animal meal, or other animal protein source, largely depends on the freshness of animal by-product before rendering. The time between collection and rendering should be as short as possible.  
• Use cold storage to prevent microbial growth: Cold storage can prevent microbial growth in products that are fresh, but if a product endures high temperatures before freezing, amines can form and continue to form once cooled.
• Practice good hygiene: Ensure transfer and processing equipment is kept sanitary to reduce microbial load. 
• Use freshness control treatments to prevent microbial deterioration: ALLINSUR™ FS has been shown to effectively control biogenic amine formation in raw materials. Click here to learn more about ALLINSUR.
